Title: Transmitter-receiver for submarine acoustic communication data
Inventor: KAMATA HIROSHI
IPC: G01S3/86
Filed: 1989-09-25
Abstract: PURPOSE:To attain stable data link with acoustic communication even at a shallow sea area by selecting other frequency before an interference wave comes due to multi-pulse so as to apply frequency sweep thereby preventing the occurrence of fading. CONSTITUTION:A transmission circuit of a transmitter of a submarine acoustic communication data transmitter-receiver is so constituted that an output is fed to a transmitter 5 via a power amplifier circuit 3 and a tuning circuit 4 from a sweep generator 2 controlled by an output data of a microprocessor 1. A detection circuit is provided to the reception circuit of the receiver, which generates a local oscillation signal to trace a transmission frequency and extracts only an FSK signal from the reception signal. Since the transmitter applies frequency sweep and the frequency is selected into other frequency before an interference wave comes due to multi-pulse to the receiver, signal fading is not caused.

Title: Rotary cutter
Inventor: ASANUMA KIYOSHI
IPC: B23C5/02
Filed: 1987-10-01
Abstract: PURPOSE:To contrive cutting only of burrs, in a cylindrical rotary cutter for machining a work while contacting the outer circumferential face thereof with the work, by arranging a cutter section which contacts with the work and cuts the work and a cutter guide section on the outer circumferential face. CONSTITUTION:A U-shaped notch is formed in the outer circumference of a cutter section 13, then a wire material 16 is wound such that it will be flush with the outer circumference of the cutter section 13 thus providing a guide section 17. Then a rotary cutter 11 is rotated to contact the circumferential face of the rotary cutter body section 12 with a burr W1 of a work. Consequently, the burr W1 is cut by the cutter section 13, and when the rotary cutter 11 is brought near to the work W, the burr W can be cut entirely. If the rotary cutter 11 is further pushed against the work W, the guide section 17 contacts with the work W thus regulates movement of the rotary cutter 11 toward the work W. Consequently, only the burr W1 can be cut down without cutting the work W itself.

Title: Servo signal detecting device for optical pickup
Inventor: NAITO MASAFUMI
IPC: G02B7/28
Filed: 1986-10-20
Abstract: PURPOSE:To prevent offset due to the change of ambient temperature, or secular change, from being generated, by taking out a detected value proportional to the area of a beam of light radiated on each block respectively of the photodetecting plane of an optical detector, and obtaining the servo signal of an optical pickup by digital operation. CONSTITUTION:When a laser beam reflected on the signal plane of an optical disk is projected on the photodetecting plane of the optical detector 11, plural photodetecting elements 11a-11d arranged at the blocks A-D of the photodetecting plane 12 represent binary value (1 and 0) states corresponding to the presence/absence of photoirradiation. Therefore, in each of the blocks A-D, the number of photodetecting elements 11a-11d in proportion to the area of the photoirradiation go to 1s, and each of counting circuits 14a-14d counts the number of the photodetecting elements 11a-11d photoirradiated in a block unit, and outputs a counted value as a digital value. The digital operation is performed at precribed arithmetic circuits 15-17 based on those digital values, thereby, the servo signal of the optical pickup can be obtained. In such way, the off-set due to the change of the ambient temperature, or the secular change can be prevented from occurring.

IPC: H04B3/06
Filed: 1991-09-27
Abstract: PURPOSE:To make high precision line equalization possible by taking the difference between the output from a reference waveform derivating means and the output from an equivalent arithmetic means to generate an error signal. CONSTITUTION:Based on the input from the A/D converter 1 sampled at a clock of nf which is n times the data modulation rate f and an error signal E, equivalent arithmetic means 2 carries out equalization adatively at a clock frequency of nf. The output from this means 2 is thinned out by a thinout means 3, and as a result, when the output rate nf of a means 2 is converted into receiving data modulation rate f and is output, while at the same time the output is supplied to a reference waveform derivatin means 4. Further, based on the difference in output between means 4 and means 2, an arithmetic means 5 generates an accurate value of signal E for every synchronization of nf, and the resultant value is supplied to means 2. With this, correlations are obtained for all of polarity signals, thereby being able to carry out high precision line equalization.

Filed: 1983-12-29
Abstract: PURPOSE:To reproduce a sound signal even at the time of reproduction of a variable speed of a VTR by storing once a reproduction sound digital signal, and reading the signal from the memory while the reading address counter of the memory is reset compulsively. CONSTITUTION:When a RAM(A)12 operates writing, a RAM(B)13 operaters reading. On the other hand, when the RAM13 operates writing, the RAM12 operates reading. By delaying the clock signal of a reading address counter 20 from an input terminal 22 more than that of a writing address counter 19 from an input terminal 21 at this time, read-out of the signal from the RAM(A)12 or the RAM(B)13 is delayed, and the extension of a reproduction sound digital signal is executed. By executing the switching by a switching signal 18 so as to read the signal from the other RAM when read-out of the signal from one RAM terminates, the sound digital signal which is recorded by compression is extended, and is inputted to a DA converter 14 as the original sound digital signal.
